  • the present disclosure relates to grip accessories for handheld devices such as handheld mobile electronics and mobile phones.
  • Described herein are improved grips for handheld devices in that the grips disclosed herein overcome many of the technical problems (such as ergonomic problems) found in known grips for handheld devices.
  • an articulated grip described herein can overcome some of the technical problems that may occur in the grips described in United States Patents 8,560,031 and 9,787,348.
  • problems with known prior art grips is that such prior art grips lack the low profile compactness and related benefits ergonomic benefits of allowing a minimal finger separation of some of the articulated grips described herein. This is due to the prior art grips’ use of cone-like accordion shaped extension members.
  • Prior art grips also lack the ergonomic benefits of an elastomeric compliance of a button top with respect to the base that helps spring load a user’s fingers with a comfortable yet secure grasp and feel such as used by some of the articulated grips described herein. Also, prior art grips lack integrated lost and found features and markings that some of the embodiments of the disclosed grips include. Such disclosed grips can have directions for returning a lost item and/or a unique identification number allowing referencing to find an owner of a grip or a device attached to a grip.
  • prior art grips lack the ability to quickly change out a personalized cosmetic top using a simple adhesive attachment approach, that uses a small and simple cosmetic disc or skin and is thereby low in costs and quick to change out with a variety of alternative cosmetic discs for personalization of the grip’s cosmetic looks — such as included in some of the embodiments of grips described herein.
  • prior art grips lack special means for mounting a handheld device to a device base or interface of a grip to make the grip highly secure and enabling a device grip with compatible mount that is capable of staying secure in a highly dynamic environment where accelerations may exceed many times the acceleration of gravity and acceleration loads may be present in six axis (X, Y, Z, roll, pitch, yaw) — such as included in some of the embodiments of grips described herein.

It also incorporates features to form a hook using the movable links that allow the phone to be hung on various surfaces such as a computer monitor top edge or a lamp shade top edge to hold the phone in a hands-free way and allow the user to use a camera of the device for photos or video applications while hands-free.
  • Ergonomic grips are beneficial to many users, including especially those with arthritis or those with small hands or weak muscles in their hands, as many mobile phones are getting larger and heavier. And, since many users now use their mobile phones for extended periods of time each day, even average users can benefit from improved grip ergonomics.
  • Ergonomic grasping of a mobile phone can also benefit from allowing the users fingers to maintain as natural of location as possible and not requiring the user’s fingers to split apart at a significant angle when using the articulated grip.
  • a grip enabling a minimal separation of the user’s fingers while holding their mobile phone is a feature of embodiments described herein.
  • an ability to mark surfaces on the grip to add “if found” return directions and a unique identification number for the user’s specific device allowing the finder to contact the mobile phone’s owner if the phone is found is a valuable feature included in some embodiments. Placing these return directions and a unique identifier on a visible surface external to the mobile phone and on the grip enables this simple “lost and found” feature and is one the features of some embodiments.
  • an articulated grip that has an extensible button top type finger retainer that can also support a mobile phone at an angle when set on its long side on a flat surface to enabling viewing the phone display screen in landscape orientation or supporting the phone at an angle when it is set on a flat surface in contact with its short side to enable viewing the phones display screen in portrait view orientation is also useful and is another feature in some embodiments.

This is the compact configuration.
  • FIG. 4 One disadvantage of the embodiment shown in Fig. 2 and Fig. 3 is that the finger retainer outer most radial edges are fully exposed and easy to catch or snag on objects the phone may come into contact with. Therefore, a more complex version of an articulated grip is shown in the alternative embodiment as seen in Fig. 4 where the phone mount base3 is swapped out with a recessed phone mount base 4 that is flush with the outer edges of the finger retainer 1 when as viewed in the top view shown in Fig. 4 with the extended configuration, and as in Fig. 7 when in the compacted configuration.

  • a clearance area allowing a user’s fingers can be placed around either side of the pivot link 2 and the finger retainer 1 will constrain the recessed phone mount base 4 to be in close proximity to the other side of the user’s fingers (usually the palm side). This is the first translational degree of freedom constraint.
  • the pivot link 2 engaged between the user’s fingers also limits the pivot link motion with respect to the user’s finger gap and constrains at least one (normal to finger gap) and in some grip cases (depending on pressure and friction) two degrees of translational freedom (also parallel to finger gap) of the mobile phone with respect to the user’s hand. Because of the aforementioned structure, the articulated grip can constrain up to three translational degrees of freedom of the handheld mobile phone with respect to the user’s hand. This can aid in the user grip and control of the attached handheld mobile phone 8.
  • the finger bracing chamfer 31 shown in the recessed phone mount base 4 between the top surface plane closest to the mobile phone, and the top surface closest to the finger retainer 1 can provide a smooth ledge that the user’s index finger can rests on, aiding in constraining the rotational degree of freedom of the recessed phone mount base 4 and the attached handheld mobile phone 8 as well, about the pivot link central axis along its length based on the user’s index finger contact constraint.
  • FIG. 12 shows a typical grip of a mobile phone using this articulated grip, helping to visualize the degrees of freedom constraints (X, Y, Z, roll, pitch, yaw) of the mobile phone with respect to the user’s hand and fingers 9.
  • the curvature of the user’s fingers controllably secures the mobile phone to the user’s hand with an additional two degrees of freedom (tilt up/down and left/right of the palm) thereby constraining six degrees of freedom of the mobile phone to be secured to the user’s hand position and orientation or pose.
  • the phone can be fully secured to the user’s hand without the user’s thumb, that frees up the thumb to be used by the user to operate the touchscreen controls displayed on the front side display surface of the user’s handheld mobile phone. With such functionality, one handed retention, positioning, orientation and control of the user’s handheld mobile phone is enabled and made convenient and secure.
  • a user with smaller hands and shorter fingers may have difficulty making contact between the tip of their thumb and the handheld mobile phone 8 touchscreen in all locations on the touchscreen.
  • This setback has been compensated for by providing a magnetic attachment option of the recessed phone mount base 4 to attach it to the back surface of a phone (which is in the opposing direction to the touchscreen side of the phone).
  • Such a feature allows the location of the recessed phone mount base 4 to be user controllable based on a user’s phone use requirements or preference, anywhere within the area defined by the size of ferromagnetic sheet with adhesive backing 12 located on the back of the phone, and magnetically retained by magnets 1 1 attached to the bottom surface of the recessed phone mount base 4, as shown in Fig. 9 and Fig. 1 1.

  • Fig. 25 shows a side view in section aligned with the axially symmetric mount centerline, illustrating the fit of the exemplary embodiment of the phone mount base 3 with the mobile phone mount, and illustrating the engagement of the base engagement barbs
  • Fig. 24 further illustrates a side exploded view of the exemplary embodiment for the mount and a clip-in mount compatible with the exemplary embodiment of the grip. And, shown at the bottom is the two-sided adhesive tape 5 disc that adhesively mounts the recessed phone mount base 4 to the back of a user’s handheld mobile phone 8 or case of the phone.
  • the recessed phone mount base and the base bottom undercut 22 provides an annular disc with a radiused transition into the taper of the recessed phone mount base 4 surfaces that allows engagement with the annular mount clip with spokes 24 near the end of each of the clip spokes 27 using a base engagement barb 23 feature at the end of the spoke.
  • the base engagement barb is sized and shaped to wrap around and contact the base bottom undercut when the phone and grip is pressed on to the mount in an axial symmetric orientation.
  • the clip spokes 27 use a tapered thickness section designed to flex as a cantilever beam in its first mode of bending to allow each spoke’s end, including the base engagement barb 23, to flex radially outward as the annular mount clip with spokes
  • Fig. 25 further depicts the main mount related relevant parts only and the recessed phone mount base 4 without the pivot Iink2 or finger retainer 1.
  • the tip of the base engagement barb is tapered down toward the mobile phone side at approximately a 30 to 60 degree angle from horizontal, so that when a user pulls up on the mobile phone with an exemplary embodiment extensible grip, the base engagement barbs have some component of force in the outward radial direction thereby causing them to flex outward increasing the effective diameter of the base engagement barb 23 (which can be annular) such that the mobile phone and securely attached recessed phone mount base can pull out of the mount.
  • This design allows the mobile phone to be removably secured at the base of the grip, near the mobile phone device, making the phone capable of being snapped in or out of the mount by pulling on the phone, in a direction normal to the display face of the mobile phone.
  • This technique allows the mount to secure the grip and mobile phone attached thereto in a secure way, constraining five degrees of freedom firmly (X, Y, Z, roll, pitch) and the sixth degree of yaw freedom firmly but rotationally twistable for orientation control by the user if desired by overcoming the yaw axis friction constraint between 22 and 23 that retards inadvertent yaw rotation about the axial symmetric centerline axis of the mount and normal to the phone back face.
  • the annular mount clip with spokes 24 is aligned coaxially and ultrasonic welded or fastened to the annular mount cover 25 that protects the annular mount clip with spokes 24 and provides a cosmetic cover surface.
  • the annular mount cover 25 is then attachable to a smooth flat surface where the mount will be affixed as decided by the user, using the mount fixing double-sided adhesive tape disc 26.
  • the annular mount cover 25 and the mount fixing double-sided adhesive tape disc 26 can be replaced with alternative embodiments to allow other attachment means such as for instance a flexible ball mount or other suitable mount attachment means for affixing the mount to the user’s vehicle attachment surface.
  • Fig. 25 also illustrates a view of the base protrusion for snap retention 21 formed into the recessed phone mount base 4, shown on one side of the skewed section view.
  • the user can install the articulated grip on the handheld mobile phone 8, and the user has multiple options.
  • a first option for installing the articulated grip on the mobile phone 8 is to use the two-sided adhesive tape 5 to adhesively attach the bottom surface of the recessed phone mount base to the back surface of the handheld mobile phone 8 or a case that will surround and protect this handheld mobile phone 8.
  • Fig. 8 shows two-sided adhesive tape 5 (which can be the die-cut) exploded below an articulated grip 10.
  • Fig. 16 shows a comparable illustration for the exemplary embodiment.
  • One side of the two-sided adhesive tape is placed against the bottom surface of the recessed phone mount base 4, and the other side of the two-sided adhesive tape 5 is exposed then secured to the back side of the handheld mobile phone 8 or its case, in a location selected by the user (e.g., centered by the user on the back of the phone or case).
  • This mounting approach has the advantage of being more secure for the mounting of the articulated grip to the handheld mobile phone 8.
  • a second option for installing the articulated grip on the mobile phone 8, but not incorporated in the exemplary embodiment is to attach the ferromagnetic sheet with adhesive backing, securing it to the back surface of the handheld mobile phone 8 or its case.
  • the two-sided adhesive tape is not used in this mounting configuration.
  • the bottom surface of the recessed phone mount base 4 has a plurality of small high energy product magnets fixed to the recessed phone mount base, as shown for example in Fig. 9 as magnets 11.
  • the user can then place the bottom surface of the articulated grip against the front ferromagnetic sheet surface, attached to the phone, at a location on the back of the phone that is selected.
  • This mounting approach has the advantage of allowing the placement location of the articulating grip to be varied and easy to change.
  • the user then can insert two of their fingers, such as the index finger and middle finger over the recessed phone mount base 4, and under the finger retainer 1 and partially around the pivot link 2.
  • the user can then find a comfortable and secure grip between their hand and fingers 9 and the handheld mobile phone 8 by slightly bending their fingers such that the back side of their fingers away from their palm contacts the finger retainer 1 and their finger-tips contact one side of the back of the mobile phone 8 and the base of their fingers and/or the palm of their hand contacts the opposing side of the handheld mobile phone 8.
  • a grasp and holding configuration for the handheld mobile phone 8 by the user while using the articulated grip device is shown in Fig. 12.
  • This configuration makes the grasping of the phone more secure and holding and orienting the phone can be done with less effort due to the mechanical constraints of the articulated grip constraining excessive degrees of freedom and retaining the fewer necessary degrees of freedom of the handheld mobile phone 8 with respect to the user’s hand and fingers 9.
  • Fig. 26 shows the grip configured for stand mode supporting the mobile phone at a particular viewing angle while on a flat surface, allowing the user to view the phone’s video screen in landscape orientation.
  • Fig. 27 shows the grip configured for stand mode supporting the mobile phone at a particular viewing angle while on a flat surface, allowing the user to view the phone’s video screen in portrait orientation.
  • Fig. 28 shows the grip configured for hanger mode supporting the mobile phone at a particular viewing angle while the finger retainer hooks over a flat edge with a perpendicular front surface, such as a computer monitor, lamp shade or book binding end thus allowing the user to fix the phone’s location and orientation and use the camera hands-free for photographic or video applications.
  • the user can also place the handheld mobile phone 8 on its long or short side in order to support it statically on a flat surface such as a table, for the purposes of tilting the display screen toward an opposing viewing location so the user can watch videos or movies on their handheld mobile phone or smartphone device. This can be done in a landscape orientation as illustrated in Fig. 26 or in portrait viewing orientation as illustrated in Fig. 27. Further, if the user wants to use the camera on the handheld mobile phone as a live streaming video source, as is often done with smartphones, the user can place the finger retainer 1 into the finger retainer recess 13 to constrain the pivot link 2 rotation and provide a hanger hook-like feature.
  • the user can then hook the finger retainer 1 over the top edge of a relatively thin flat topped object, such as a computer monitor as illustrated in Fig. 28, or a lamp shade, book binding top end surface or some automobile steering wheels.
  • a relatively thin flat topped object such as a computer monitor as illustrated in Fig. 28, or a lamp shade, book binding top end surface or some automobile steering wheels.
  • the compressed configuration is achieved by pushing and rotating the finger retainer 1 toward the recessed phone mount base 4, and as a result, inducing a rotation of the revolute joints at both ends of the pivot link 2 such that the finger retainer 1 and pivot link 2 and recessed phone mount base 4 have a parallel top surface and the configuration as it is shown in Fig. 10.
  • this can result in the pivot link 2 elastomer bump snap protrusion 20 deforming and passing past the base protrusion for snap retention 21 , and as a result, causing the finger retainer to snap into place and be retained in the compact configuration as it is shown in Fig. 20.
  • embodiments of the articulated grip can enhance the ease of gripping, holding and orienting a handheld electronic device, such as a mobile phone, when it is in its extended configuration, and it provides advantages of compact storage when collapsed. It also provides advantages of improved ergonomics, personalized and easily changed cosmetic looks, ability to incorporate markings providing directions and unique identification enabling a lost-and-found return ability, compatibility with a secure mount features, statis orientation of the phone tilted at an angle to enhance viewing in landscape or portrait orientations, and a hanger feature that allows hands-free support of the user’s device that enables improved video and photographic capture possibilities.
